본 논문은 서베이 데이터를 이용하여 한국의 연료유형에 따른 자동차의 잠재적 수요를 분석한다. 종속변수는 휘발유, 경유, 하이브리드, 전기, 수소를 포함한 향후 희망 자동차 연료유형이며, 주요 설명변수는 응답자의 인구학적 특성과 희망 자동차 연료 유형 선택 시 고려사항, 주성분분석으로 추출한 환경에 대한 인식이다. 다항로지스틱모델을 이용한 분석결과는 다음과 같다. 연비와 운행편의를 고려하는 응답자들의 하이브리드차에 대한 수요는 높아지는 반면에 전기차와 수소차에 대한 수요는 낮아진다. 환경에 대한 부정적인 인식이 있는 응답자들의 휘발유차와 경유차에 대한 수요는 높아지는 반면 전기차에 대한 수요가 낮아진다. 환경에 대한 우려를 표하는 응답자들의 하이브리드차에 대한 수요는 증가하는 반면에 전기차에 대한 수요는 감소한다. 이와 대조적으로, 환경 친화적인 응답자들의 경유차에 대한 수요는 감소한다.

This paper presents a generalized fuel choice model in which restrictive constraints on cross-price coefficients as Baughman-Joskow-FEA Logit Model need not be imposed, but all demand elasticities are uniquely determined. The model is applied to estimating aggregate energy demand and fuel choices for the residential and commercial sector. The structural equations are estimated by a generalized least squares procedure using national-level EPB, KDI, BK, KRIS, MOER data for 1965 and 1980, and other related reports. The econometric results support the argument that “third-price” and “fourth-price” coefficients should not be constrained in estimating relative market share models. Furthermore, by using this fuel choice model, it has forecasted energy demands by fuel sources in, the residential and commercial sector until 1991. The results are turned out good estimates to compare with existing demands forecasted from other institutes.

This research examines the spatial development of rural industrial estates (Nong-gong Jigu) in Chonbuk province and gives insight into the strategies for economic development in the entire region. Selected location factors which are likely to pull new investment into the estates are examined by using questionnaires. Few loction factors except nonlocal factors can be found in explaining why location choices are made. The irrelevance of the analysis based on location factors suggests that an alternative approach should analyze changes in the spatial development of the rural industrial estates. Such an alternative is to understand the dynamics of the spatial organization of production by focusing on characteistics of plant closing in the rural industrial estates. To take into account of the characteristics of plant closing we provide the hypothesized relationships between employment size, organizational structure, inter and intra industrial linkage, characteristics of production processes, and availability of local labor market and the likelihood of closing. A logit model is then made to identify the selected factors which might influence the probability of plant closing. The results from the logit analysis and their implications suggest that the policy should be more concerned with the characteristics of firms, such as size and ownership, as well as of the local labor markets. Given that the Chonbuk region has experienced rapid population decline, together with its poor industrial base, it seems that the success of the policy in the declined rural areas in less certain.

패널조사에서 패널탈락이 특정계층에 집중되어 있다면, 초기에 구축된 샘플의 변화에 따라 패널자료의 대표성에 문제를 야기할 수 있다. 본 연구는 대졸자 직업이동 경로조사(GOMS)를 이용하여 신뢰성과 대표성을 저해하는 표본 탈락편의(non-random attrition bias)가 있는지를 파악하고, 패널탈락의 결정요인을 분석하여 패널탈락을 최소할 수 있는 방안을 모색하고자 한다. 분석결과 패널탈락은 응답자의 문제보다 조사시스템의 문제가 더 큰 것으로 나타났다. 따라서 추가연구를 통해 체계적인 조사시스템의 구축 및 응답자관리방법 개발뿐만 아니라 패널탈락의 편의를 보완하기 위한 가중치 부여 등 다양한 개선책의 도입이 시급한 것으로 판단된다.

This study analyzed the effect of consumer value and unethicality on the type of consumer complaint behaviors. Despite the obvious importance of the research on consumer complaint behaviors focused on consumer's inherent personality, there is relatively little work done. The purpose of this study is to analyze the determinants of consumer complaint behaviors in order to improve consumers' well-being and develop the market condition. The 1,050 respondents are finally analyzed using the descriptive statistics, factor analysis, and multinominal logit model. Consumer value and unethicality are significant effect on the type of consumer complaint behaviors such as no action, private action only, public action only, and both private and action. The orientation of achievement and pleasure among consumers' value is associated with the higher level of complaint behaviors compared with no action. In terms of consumers' unethicality, no harm unethicality is associated with the types of each consumer complaint behavior except no action. On the other hand, both proactive and passive unethicality increase the possibility of no action. The policy implications of the consumer education are suggested as well as the directions of customer management strategies in the business sector.

본 연구는 국내에서 가장 실질적인 산학협력 사례 중 하나인 IT멘토링 사업에 참여한 524명을 대상으로 그 효과성과 그 영향요인에 대하여 가설을 세워 검증해 보았다. 검증결과, 산학협력에 참여하는 주체인 학생, 산업체 전문가, 지도교수는 물론 산학협력을 지원하는 제도와 인프라 요소 모두 산학협력에 일정한 영향을 끼치고 있음을 알 수 있었다. 또한 IT멘토링에 대한 기업 및 대학의 만족도 영향요인을 분석하기 위해 로지스틱 회귀 모형을 적용하였다. 기업의 만족도는 학생들이 프로젝트 참여에 적극적이고 멘토링을 통해 학생들의 전공역량이 향상되었다고 인식되었을수록 높아지고 있음을 알 수 있다.

본 연구에서는 경산시 대중교통체계 개편 전과 후의 통행패턴을 분석하였으며, 통행패턴 변화의 통계적 검정을 위해 카이제곱($x^2$)검정과 t-검정을 실시하였다. 또한 대중교통 이용자들의 통행패턴 변화에 영향을 미치는 요인을 파악하기 위해 이항로짓모형을 추정하였으며, 개편 전 후 교통수단 선택에 영향을 미치는 요인을 비교 분석하기 위해 다항로짓모형을 추정하였다. 이들 두 로짓모형의 추정을 위해 사용된 설명변수로는 통행패턴 변화 및 대중교통체계 개편 전 후의 교통수단 선택에 영향을 미칠 것으로 예상되는 성별, 연령, 직업, 통행목적, 요금지불방법, 목적지, 통행시간의 7개 변수를 사용하였다. 이러한 분석을 통해 대중교통시설 및 환승체계 구축 등 교통정책 수립에 필요한 다양한 시사점과 본 연구의 한계를 제시하였다.

The main purpose of this study is to explore the factors that affect the transformation of over-depopulated rural villages. Specifically, we investigated the reasons of the rapid decrease in the number of over-populated rural villages shown by recent census data in spite of the continuing decrease of population in rural area. We used a binary-logit model and the Census of Agriculture, Forestry and Fisheries data(2010, 2015). The main results are summarized as followed: First, the over-depopulated rural villages with strong agronomic base are more likely to exit from over-depopulation. Second, returners from urban to rural have a positive impacts on the revival of over-depopulated rural areas. Thirds, improving the basic services accessibility of rural residents is also critical for keeping rural community more sustainable. These findings can be used to make effective strategies to revive the depopulated rural villages.

The aim of this study is to empirically identify the differentiating characteristics of determinant factors on sing-person households' commuting mode choice compared to multi-person households' one in order to establish the customized police directions to decrease private car use in commuting. While the study use the 2% sample survey data on the population and housing in 2015, it employ multinomial logit models on relative choice probability of such alternative commuting modes as bus, subway or rail, and walking, rather than driving. As potential determinant factors, the study employs demographic, socio-economic, and housing and residential one for both models of single-person and multi-person households. The study finds that the behavior of commuting mode choice has distinctive difference by gender, marriage status, physical activity constraint, job type, residential period in current housing of the single-person household's workers compared to the multi-person households' ones. Based on the findings, the study deduce ten commuting policy directions customized for the single-person household.

This study was designed to examine, applying Rasch analysis based on item response theory, the questionnaires of the Activities-Specific Balance Confidence (ABC) scale for the elderly. The subjects were 99 institutional older adults and clients of social welfare facilities. The subjects (17 men, 72 women) ranged in age from 65 to 94 years (mean age 76.5 yrs). The Winsteps software was used to assess whether the ABC scale fits the Rasch model, to estimate the score and to refine the rating scale. The results are as follows. Twenty-two subjects were excluded as misfit persons. Four items were found to be misfits and the order of difficulty of the remaining 12 items was rearranged. Their balance confidence is indicated by -.64~1.12 logit, and the transformation formula is score=[(logit score+2.76)/(2.76+3.48)]${\times}$100. The most difficult item was "Walk outside in icy sidewalks" and the easiest item was "Walk around house." In conclusion, the ABC scale for the elderly has been proven reliable and valid. Therefore, it is expected to be used as an effective examination tool for treatment planning and screening for older adults.
